Node.js development: coordinate exchanges between your services
An application may depend on several services, frequent exchanges or event-triggered processing. AXELITES supports Node.js development starting from these interactions. We describe circulating data, expected responses and behaviors to plan when a service does not respond.
Applications built around your work
Organize the exchanges that make your application work
Documented APIs
Entry points, formats and errors are described for client applications. Changes consider existing consumers and any adaptations they may need to support.
Event-driven exchanges
Events and their effects are defined according to business needs. Duplicate risks and processing dependencies are examined to preserve understandable system behavior.
Error handling
Failures are distinguished according to cause and consequences. Responses, alerts and recovery options are planned to avoid lost operations without usable information.
Processing monitoring
Operating information connects a request to its stages. Its detail level is selected to facilitate diagnosis without unnecessarily collecting sensitive data.
How we move forward together
Map interactions
We identify the services, events and applications involved. Exchanged data and user expectations describe each component's responsibilities in overall operation.
Define contracts
Interfaces specify inputs, outputs and errors. External service availability constraints are considered before building the processes depending on them.
Build and test
Functions are developed using representative scenarios. Interruptions, incomplete responses and repeated events are checked alongside journeys that run normally.
Prepare operations
Configurations, procedures and diagnostic information are organized. Teams have guidance to track processes and understand incidents after launch.
A prioritized first release with an agreed budget and acceptance criteria.
Your questions, our answers
Practical answers to help you make the right decisions before starting your project.
Discuss my projectThe choice depends on the nature of the work, load and architecture. An exchange-oriented service has different constraints from intensive computation. We examine planned operations to avoid choosing a technology based on a general performance promise.
Yes, the project can define the services needed by the application, with expected data, access and errors. Interface evolution must also be planned when several mobile versions remain in use. This constraint influences design choices.
The event source and possibilities of repetition must be examined. Depending on the processing, identifiers and controls can recognize an operation already executed. These rules must be defined with business consequences in mind, since duplicates do not always have the same impact.
